ta ghi ra giấy theo kiểu dọc thẳng ta duoc a = 2 b = 8 c = 6 ket qua la 286

8abc - abc8 = 5418

=> ( 8000 + abc ) - (abc x 10 + 8) = 5418

=> 8000 + abc - abc x 10 - 8 = 5418

=> 8000 - 8 - 5418 = abc x 10 - abc

=> 2574 = abc x 9

=> abc = 2574 : 9

=> abc = 286

8abc- abc8 5418. Đáp án là:a=2,b=8 ,c=6.Tích đúng cho mình nhé :)

8abc - abc8 = 5418

8000 + abc - abc x 10 + 8 = 5418

abc x (10 - 1)= 8000 - 8 - 5418

abc = 2574 : 9

abc = 286

8abc - abc8 = 5418

8000 + abc - abc x 10 + 8 = 5418

tk mk nha mk nhanh nhất

.....

8000 + abc - 10 x abc - 8 = 5418

7992 - 5418 = 10x abc - abc

2574 = 9 x abc

abc = 2574 : 9

abc = 286

vậy 8286 - 2868 = 5418
